IMPROVEM ENT IN STRAW CUTTERSV.

Specification forming part of Letters Patent N0. 49, [90, dated August l, 1865.

To all whom it may concern.-

Be it known that I, GEORGE T. Wn1Gn'r,of Cincinnati, Hamilton county, and State of Ohio, have invented certain new and useful Improvements in Straw-Cutters; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying' drawings, making part of this specification, in which Figure 1 is a perspective view of a machine embodying my improvements, and Fig. 2 is alongitudinal section of the same.

A represents a frame supporting a box or trough, B, in which the straw is placed before being cut.

C is a iiy-whecl attached to the shaft c, and gearing with a pinion, D. y

The pinion-shaft d has firmly secured to it the eccentrics E E', which revolve in concave recesses in the vibratory cross-heads F F.

,G G are straps which encircle the upper portions of the eccentrics E E, and are secured at both of their'lower ends to the vibratory cross-heads F It", so as to form ayoke surrounding the ecccntrics E E, with which they have a corresponding vibratory movement.

The cross-heads F F are pivoted at their cen-i ters to the gate H, which is confined to a vertical path by means of the grooves g g.

Attached to the gate H is the knifeI, which is set at a suitable angle to insure a shearcut 7* action.

J is a stationary knife secured to the bottom of the box B.

, tion of the roller is desired.

K is a corrugated feedroller, which, in connection with the lower roller, L, serves to feed i the straw between the knivesIand J. Theshaft ofthe feed-roller Khus attachedto it aratchetwheel, O, which is rotated by the pawl P.

R is a slotted arm, journaled at one end to the shaft of the feed roller K, and provided with a slot, r,which is traversed by theadjustable stud or wrist S.

T is a disk, havinga series of apertures, tt', situated at dierent distances from the center of the disk, and the speed of the feed-rollerK is regulated by inserting the wrist S in the aperture nearest the center, or inv the outer orin termediate ones, according as aslow or fast mo- U is one of two springswhich press the roller K firmly down on the straw, so as to insure its receiving a positive forward motion between theknives I and J.

I claim herein as new and of my inventioni The arrangement of the ratchet-wheel O, pawl P, in combination with the slotted arm R, and perforated disk T, for graduating the i rotation of the feed-roller K,in the manner de-l scribed.

In testimony of which invention I hereunto set my hand.
